I have a Heath 4221 oscilloscope in need of repairs. This one is apparently not a Heathkit and appears to have been manufactured in Japan. Does anyone out there have any suggestions as to where I might take it (in the San Francisco bay area) or even find a schematic ?
ME TOO! I have a 4221 which powers on and the CRT heater comes on bu it displays no trace. A schematic would be great.

Have you tried contacting Heath? They still have a lot of their manuals and schematics available.

Hi...
The exact model number you guys are looking for isn't here, but
4221 is surrounded... (4210 and 4225). Maybe one is close enough to get you started? Or maybe the owner of the site can help.Be forewarned though, these aren't freebies, they cost.
Take care.
